Title: Process for the removal from the moulds of roughly moulded objects in the manufacture of paper objects moulded by suction and a machine relating thereto
IPC: D21J3/00
Filed: 1947-08-27
Abstract: 659,813. Moulding articles from paper pulp. MARGUERAT, G. Aug. 27, 1947, No. 23779. Convention date, Nov. 30, 1943. Addition to 659,062. [Class 87 (ii)] In a machine as claimed and described in the parent Specification, a number of articles are simultaneously moulded by means of a number of moulds 2 carried by a common carrier 1 and to ensure that the premature removal or bursting of one article will not substantially reduce the available air pressure for removing the remaining articles, the compressed air for this purpose is delivered to each mould from a common chamber 4 through means individual to each mould, as shown valves 10, for reducing the pressure in the moulds below that reigning in the chamber 4. A sudden drop in pressure in one mould does not then substantially affect the pressure in the remaining moulds. The compressed air is fed to each mould by a tube 9 extending near to the base of the mould and suction for moulding is applied through a concentric tube 7 from a second chamber 3 in the mould carrier, communicating with a suction pump by pipe 6. Specification 651,205 is referred to. The Specification, as open to inspection under Sect. 91, also states that when a moulded article has been detached from its mould and deposited in a female receiver, before the article is returned to the mould by applying a slight suction the mould is withdrawn slightly upwards so that the article returns to it in a new position. This is stated to facilitate subsequent removal. It is also stated that the interior of the mould may be provided with an elastic diaphragm to facilitate returning the article to the mould at the desired height. This subject-matter does not appear in the Specification as accepted.

Title: Hydraulically operable reciprocating motor
IPC: F16K11/07
Filed: 1971-04-19
Abstract: 1349083 Hydraulic reciprocating motors FRIEDRICH UHDE GmbH 19 April 1971 [12 March 1970] 23915/71 Heading F1A An hydraulic reciprocating motor comprises a reversing valve 1 controlling the supply to and exhaust from opposite ends of a cylinder 2, the reversing valve being changed over by liquid directed to alternate actuating chambers 4 by respective spring-loaded pilot valves 3, 3' actuated at the ends of each stroke by members carried by the piston rod. In the neutral position of the valves 1, 3, 3' shown, springs in the valves 3, 3' cause both chambers 4 to be isolated. On displacement of say the valve 3', the right hand chamber 4 and the actuating chamber of the valve 3 become pressurised from a source S. Thus the valve 3 is moved upwardly against the action of its spring, whereby the left hand chamber 4 and the actuating chamber of the valve 3' are connected to a return R. This causes the valve 1 to reverse, valve 3' being maintained displaced by its spring. In Figs. 5 and 6 (not shown), two motors operate in parallel with their lines V<SP>1</SP> interconnected.

Title: Automatic container filling control method and apparatus
IPC: B67C3/06
Filed: 1966-05-27
Abstract: 1,080,437. Bottling &c.GEO. J. MEYER MANUFACTURING CO. May 27, 1966 [Sept. 30, 1965], No. 23936/66. Heading B8T. A counter-pressure bottle &c. filling apparatus comprises a transistor switching circuit which is sequentially operated by one switch actuated on engagement of a bottle &c. with a filling head; by a second .switch on build-up of counter-pressure in the bottle &c, and by conduction of current through liquid flowing into the nearly filled bottle &c., to control an inlet valve in the filling head. Engagement of a bottle (18), Fig. 2 (not shown), with a filling head (17), conditions a magnetic switch (22) to open and prevent current passing through a lead (4), Fig. 3 {not shown), to a first switching transistor (41), which accordingly conducts. A second switching transistor (45) to which' it is coupled is. thereby, rendered non-conducting. A latch circuit (7) connects the two transistors (41; 45).Build-up of counter-pressure in the bottle (18) opens a diaphragm-operated, pressure-sensitive, magnetic switch(28). An amplifier (11) including two transistors (46, 50) is thus rendered operative. A, relay (112) is thereby energized to open a valve (120) with filling head (17) and admit liquid to the bottle (18). When the level (30) of the liquid in the bottle (18) reaches a counter-pressure tube (24) carrying an external insulating sheath (94) and an electric probe (29) at its end, current is conducted through the still-flowing liquid to the filling head(17). Current is transmitted thence to a lead (8); and a two-transistor amplifier circuit (9), which in turn feeds the second switching transistor (46). Accordingly, the amplifier (11) is switched off, the relay (112) is de-energized, and the valve (120) in the filling head closed to shut-off the supply of liquid to the bottle (18). When the bottle (18) is removed from the filling head (17), the switch (22) is closed, to send an electric impulse through the lead (4), and  re-set the circuit ready for another cycle, when a fresh bottle is engaged .with the filling head. If the bottle (18) bursts during filling, the valve (120) is automatically closed to stop the supply of liquid.

Title: Improvements in fluid flow meter sensing units
Inventor: PARKER DENNIS AMERENA
IPC: G01F1/115
Filed: 1955-08-19
Abstract: 803,069. Driving dynamos. SIMMONDS AEROCESSORIES, Ltd. Aug. 13, 1956 [Aug. 19, 1955], No. 23962/55. Class 35. [Also in Groups XXVI and XXXVIII] A pick-up unit for a fluid - flow meter comprises a straight section of pipe of non - magnetic material containing a balanced bladed rotor of magnetic material which is rotated about a longitudinal axis by the fluid flow so that the blades come simultaneously opposite one or more pairs of polepieces secured to the pipe, these polepieces being linked to a common permanent magnet (or D.C. excited coil) by a yoke of soft magnetic material; one or more sensing coils mounted on the polepieces generates an E.M.F. when the magnetic circuit is completed by the rotor blades. In the simplest arrangement (Fig. 1) the magnetic circuit comprises the rotor blades 5 within the pipe 2, and the polepieces 6, 7, yoke 10, 11 and magnet 12, impulses being generated in the coils 13, 14 when the blades come into the position shown. In modifications (Fig. 3, not shown), a second pair of coils is mounted 60 degrees away from the first pair and connected so that the E.M.F's re-inforce each other; (Fig. 4, not shown) a six-bladed rotor has four coils so that four blades come simultaneously opposite to them; (Fig. 5, not shown), four pole-pieces successively 30 degrees apart are used, with a six-bladed rotor, the middle pair only being provided with coils. It is stated that it is possible to have only one sensing coil per pair of polepieces. In certain of the above arrangements pairs of coils may be connected so that the signals neither re-inforce nor cancel each other, e.g. if the phase difference is 90 degrees, and in this case the output is a ripple superimposed on steady D.C.

Title: Apparatus for the remote registration of the increase during a predetermined period of the number registered by an electrical counter
IPC: G06M1/38
Filed: 1956-08-03
Abstract: 823,410. Counting-apparatus; zeroizing- mechanism. SODECO SOC. DES COMPTEURS DE GENEVE. Aug. 3, 1956 [Aug. 9, 1955], No. 23966/56. Class 106 (1). In an arrangement for the remote indication of the increase during a predetermined period of the number registered by an electric impulse counter, each impulse is transmitted also to a remotely situated auxiliary reversible counter which registers zero at the beginning of the period and which at the end of the period is returned rapidly to zero by impulses from an impulse transmitter which simultaneously step on a remote counter. As shown, a consumption meter a, Fig. 1, emits impulses which are counted directly by a corresponding counter b and which also actuate a reversible counter c which is at zero at the beginning of a period, through its winding 1, thereby driving the numeral wheels 11-14, Fig. 2, in an additive direction through a differential gear 22. At the end of the predetermined period, an impulse transmitter d is started and the impulses emitted actuate the counter c reversely through its winding 1<SP>1</SP> and also step on a remote counter e. This action continues until the counter c reaches zero, when a switch 21 opens to interrupt the supply of impulses from the transmitter d. The switch 21 is actuated via arms 18, 20, the arm 18 carrying a spindle 17 on which rollers 16 are mounted contacting cam discs 11<SP>1</SP>-14<SP>1</SP> attached to the number wheels and recessed at points corresponding to the zero of the associated number wheels. In a modification (Fig. 4, not shown), the time taken to drive the counter c back to zero is reduced by replacing it by a counter in which the numeral wheels may be returned individually to zero by impulses from a transmitter and in which interdenominational carry is by electric pulses. In all cases, the reversal to zero of the c occurs while the meter a is inoperative.

In a free precession magnetometer using a solution containing atomic nuclei having a definite gyromagnetic ratio different from zero and paramagnetic ions with an unpaired electron having a saturable electronic resonance line at a frequency different from zero when in a magnetic field tending to zero in which an alternating field is applied to saturate the electronic resonance line of the latter and the unidirectional polarising field is of the same order of intensity as the field to be measured (one to ten times) a switching arrangement is provided to connect a D.C. source to the polarising field coil to quickly transfer the coil to an energy dissipating circuit and then to a frequency measuring circuit, the switching arrangement being controlled so that the period of connection of the source to the coil is of the same order as or of the period of the Larmor frequency. The saturating field for the paramagnetic ions which is in the region of 55. 8 megacycles is supplied to a coil 2 Fig. 1, comprising 4 turns of heavy gauge wire by a generator 5 through a coaxial cable 4 and a matching network 3, and the polarising field is applied to a coil 6 from a D.C. source 9 through the contacts 10 of a relay controlled by clock pulses from a generator 17. A further set of relay contacts 11 also controlled by generator 17 connects a resistor 12 across coil 6 when contacts 10 are opened to dissipate the stored energy, and then short circuits the resistor to enable the Larmor frequency to be applied through a selective amplifier 7 to a frequency and recording apparatus 15, 16. Capacitors 13, 14 tune the coaxial cable 8 to the Larmor frequency, and selective and adjustable band-pass stages are included in the amplifier to cater for different ranges of field strength to be measured. The control of relays 10 and 11 by pulses from generator 17 is achieved by a pair of double triode 20, 31 Fig. 4 to which the control pulses are commonly applied and which include the relay coils 10, 11 in series with protective or isolating condensers 25, 35 in their cathode circuits, or pulse elongating network 29, 30 being included in the grid circuit of valve 31. Terminals 18, 27 and 37 connect to apparatus 17, 6 and 7 of Fig. 1 respectively, the D.C. power being supplied from source 9 through double triode 26 the grid bias of which is adjustable by the wiper of a potentiometer 39. An alternative arrangement using transistor switches is described with reference to Fig. 5 ( not shown) and lists of suitable paramagnetic substances and component valves are included. Electric waveforms are described with reference to Figs. 2 and 3 (not shown). Speci - fications 888, 439 and 941,310 are referred to.
